新疆宏源铅锌矿找矿方法组合及成矿远景分析

Study on integrated prospecting techniques and prospecting potential for Hongyuan lead-zinc deposit,Xinjiang

新疆哈密市宏源铅锌矿位于塔里木板块北缘,中天山地块内,沙泉子深大断裂南侧,区内铅锌矿成矿条件优越,具寻找大型矿床潜力。矿体形态多为似层状、透镜状产出,近矿围岩蚀变强烈,主要为硅化、透辉石化、绿帘石化等。文章通过对矿床地质特征和成矿背景的总结,初步确定该矿床为喷流—沉积型铅锌矿床,并建立了工作区铅锌矿找矿模型,分析了寻找铅锌矿技术方法组合,为在该区寻找同类型矿床指出了找矿方向。

Hongyuan Pb - Zn - sulfide deposit in Xinjiang is located in the northern margin of the Tarim plate, the Central Tianshan Block and south of Shaquanzi deep fracture. In this area, the Pb - Zn - sulfide deposits have the advantageous minerogenetic conditions, there is great potential in search of large deposits. The form of deposit is mainly strataed, lensed. The wallroek alteration near the ore body is very thick and mainly represents siliconed, diopsided, epidoted and so on. In this paper, based on searching metallogenic background and geological features of the deposits, preliminary determination of the deposit is sedimentary exhalative deposit, established the exploration model of Pb - Zn - sulfide deposit. Analyzing for seeking for Pb - Zn - sulfide techniques combination, the ore search direction for seeking the same type mineral deposit is pointed out in the area.
